' Application November 25, 1950, Serial No. 197,587

The present invention relates to a sewing machine, presser foot forguiding a tape or ribbon fed to the sewing machine and sewed thereby asa binding or decoration on a garment.

I have disclosed a tape and ribbon tension guide attachment for a sewingmachine for which I have filed application for a patent, Ser. No.159,475, on May 2, 1950, and in which application I have described apresser foot constructed and arranged to guide the tape or ribbon to theneedle. v v v The present invention contemplates an improvement to thepresser foot disclosed in that application and which presentpressergfoot has particularuse with the attachment therein disclosed. v

The presentinvention contemplates the provision of a presser footconstructed and arranged so that the tape or ribbon fed from the spoolis guided in a positive manner to the needle so that it may not beinadvertently moved from side to side under the presser foot but will beheld so that it may not be misaligned with the garment to which it issewn.

The present invention contemplates the provision of such a presser footthat is arranged and constructed sothat the guiding means forming a partof the presser foot may be selectively adjusted to differing widths ofthe tape or ribbon which is to be sewed to the garment.

The presser foot of the present invention is such that the tape orribbon is guided to the sewing machine needle and the garment withoutrequiring attention to the position of feeding thereof that is necessarywith prior devices.

Thus, a sewing machine using the presser foot of the present inventionis relatively faster in operation and more easily operated than sewingmachines using presser foots of the prior art.

The presser foot of the present invention further permits ready cuttingof the tape or ribbon at the garment so that a uniform binding ordecoration may easily be obtained, an operation which was not possiblewith the tape or ribbon guiding devices heretofore used and which werereferred to as tube guides.

These, other and further objects, uses and advantages of the presentinvention will be clear from the description which follows and thedrawing appended thereto in which:

Fig. 1 is a side elevation of a presser-foot according to my inventionmounted on the bar of a sewing machine and showing a needle, tape orribbon and garment.

Fig. 2 is a view on the line 2-2 of Fig. 1.

' 5 Claims. I (Ci. 112--152) Fig. 3 is a View on the line 33 of Fig. 1.Fig.4 is a cross section on the line 44 of. Fig. 2.

Fig. 5-is a plan view similar to Fig. 2 with the tape or ribbon guidemoved to smallest tape limit...

Referring now to the drawing, the presser foot Ill is provided with theopen groove or slot l2 in which .is received the presser bar I4,' ';ofthe type, usually found in a sewing machine, and which presser foot issecured to the bar in a conventional manner, as by the set screw I6.

The vertical front wall l8, on the left of Figs. 1 and 4, continuesintothe horizontal presser foot plate 20, between which and. theconventional sewing machine feed plate (not disclosed) the garment 22and the tape or ribbon 24 are located to be sewn'together by the needle26. v

The horizontal presser foot plate 20 continues into the upwardlyinclined, as viewed in Figs. 1 and 4, guide support 28 provided with aforward and downward side extension 44.

Secured to the underside of side extension 44 of support 28 andunderlying the underside thereof, in any suitable manner, such astheri'vets 39,1. provide the guide plate 32. I

The guide plate 32 extends from the straight edge at the front of theguide support 28 to the rear andterminates at the bend or juncture ofthe support and the presser foot plate 29, which bend or juncture isjust in advance of the opening 34 through which the needle 25 passes forwhich slot the set screw 36 extends into a corresponding internallythreaded opening in the guide support 28 wherein it is secured.

The tape or ribbon guide 38 may thus be moved laterally between theextreme position at one end of the slot 42 illustrated in Figs. 2 and 3,and the other extreme position illustrated in Fig. 5 at the other end ofthe slot. The tape or ribbon guide 38 is held in the selected positionon the support 28 to adjust the width of the channel between the hookwall 40 and the side extension 44 and which channel is formed by thewall 40, side extension 44, plate 32 and support 38. I

Thus, the space 48 (see Fig. 3), that is the width of the entrance tothe channel, may be adjusted to accommodate therein tapes or ribbons .ofany width. In the presser root of the present invention, it iscontemplated to make the channel adjustable to accommodate tapes orribbons from one-eighth to five-eighths of an inch in width.

In operation, the space 4'6 is adjusted to accommodate the width of thetape or ribbon 24 which is inserted into the presser foot Ill and sewedto the garment 22 in the conventional manner by the needle 26.

It will be recognized that the tape or ribbon 24 is held againstsidewise movement by the hook wall 40 and the side extension 44 and socannot inadvertently be misaligned with the garment during the sewingoperation.

It will further be recognized that I have provided a presser foot havinga guiding channel, the width of which may be selectively adjusted todifiering widths of tape or ribbon that is sewed by the machine.

It will be further recognized that since the tape is positively guidedto the needle by the-action of the hook" wall and side, noattentiontothe feeding position of the tape or ribbon is necessary and that sewingmachines using presser foots' according to my inventioi-rz'nay' be moreeasily and speed'ilyope'rated than heretofore possible.-

It will still' further be recognized that by reason of the-constructiondescribed, the tape" or ribbon may becutoff at the lace orsewing whichis located at the bend formed by the pros s'er plate and th'e sul iport.

While I have shown in detail a specific" em bodiment of my invention, itwill be understood that I do not int'endto be limited thereto'but wishtoclaim my invention as broadly as the scope of the prior art and theappended claimspermit; 7
